Summarization Techniques
Extractive Summarization
Ranks sentences using position, length, and keyword cues, then retains a selection in their original order. A selected sentence can still lose important context.
Template-based rewrite
Combines a few detected phrases with fixed wording. This demonstrates a format only; a real abstractive model generates new language and also needs careful checking.
Bullet Point Summary
Presents selected sentences as bullets so you can inspect each point separately.
Key Sentences
Uses sentence length, punctuation, and position to choose candidate sentences. Decide for yourself whether they represent the main idea.
Best Practices for Effective Summarization
- Identify the main purpose: What is the core message or argument?
- Focus on key facts: Prioritize important data, findings, and conclusions
- Maintain objectivity: Avoid personal bias in your summary
- Use appropriate length: Match summary length to your needs and audience
- Check coverage: Look for missing qualifications, evidence, and conclusions
- Verify accuracy: Make sure the summary faithfully represents the original
